2015 SG cam change Zippers 525

I would look elsewhere, IIRC, intake close on the Zippers/Redshift 525 is 18*; too early IMHO for a 103" motor. Take a look at the Andrews 48, 57 or Cyclerama 575. The 48 is all about low end grunt; great for a touring bike, two up and loaded. The 57 and 575 are not "off idle" torque like the 48 but have a strong low and mid range.

Also consider the cr575 as suggested. That's the next cam I want to use. Good for stock 103 but also has potential if doing headwork. Will come on earlier that the 57 but later than the 48 which will run out of puff too early for many folks unless you're regularly carrying a lot of weight
